" 8 Claims; (01.198-220) This invention relates to improvements in shaker conveyers and has among other objects to provide a novel form of swivel connection in a shaker conveyer trough line, so arranged as to permit a maximum amount of lateral adjustable movement of one trough section of'the conveyor with respect to another and to take the side thrusts away from the supporting means for the trough sections of the conveyer, when said trough sections are positioned laterally with respect to each other.

A more specific object of my invention is to provide an articulated connection between the driving and driven trough sections of a conveyer,

including a base held stationary on the ground and a guiding connection between the driven trough section and this base, arranged to-transmit the side thrusts from the driven trough section'to the base and to relieve the trough sections and their supporting means from side thrusting forces when the driven trough section is in various lat-- eral positions with respect to thedriving trough section. Other objects of my invention will appear from time to time as the following specification prodrawings wherein:

Figure 1 is a plan view ofa swivel-constructed; in accordanc with my invention, with certain; parts broken away in order to more clearly illustrate certain details of my invention;

Figure 2 is an enlarged longitudinal sectional view taken substantially along line 2 -2 of Figure 1;

Figure 3 is a transverse sectional view taken" substantially along line 3-3 of Figure 2; and

Figure 4 is a transverse sectional 'view taken= substantially along line 44 of Figure 2.

In the drawings, the embodiment of my invencarry material around corners, or so a pick-up member on the forward end of the driven trough section may pick up material from the extreme" corners of a wide room or may be extended-along a cross cut or entry at an angle to the main part of the conveyer, to pick up material therefrom.

The articulated connection between the drivingand driven trough sections of the conveyer i'ncludes a base I 2 adapted to be firmly held-in position on the ground by means of a pluralit of '25 ceeds and with reference to the accompanying nectingtrough sections l5 and I9 and bridges the I jacks I3, l3 engageable with sockets I4, H in said base at their lower ends and with the mine roof at their upper ends. A connecting trough section 15 is reciprocably mounted-on said base on a usual form ofball frame, indicated by reference character I 8. Said connecting trough section is adapted to have connection with the forward end of the trough section I!) by means of the usual connecting bolts [1, l1 extending through abutting eyes l8, l8; f A forward connecting trough section 19- is mounted on said base and is connected at its receiving end with the discharge end of the trough section H. Said forward connecting trough section is mounted on a ball frame 20, for reciprocable and for lateral swinging movement with respect to said base and for limited pivota1 movement'about an axis extending longitudinally of th'etrough section I l, to permit said trough section to follow a transversely pitching seam with.

out twisting or binding of the parts of the swivel, as" will hereinafter more clearly a pear as this specification proceeds. Said ball frame is mounted on the forwarclend of an arm 2|, which is laterally slidable along said base and is pivotallyconnected with a flanged portion 22 of a vertical stud 23, mounted on and extending upwardly from said base.

An intermediate trough section 24 is pivotally connected at its ends to adjacent ends of the congap between said trough sections. It should here benoted that one purpose in spacing the trough sections I5 and [9 from each other and bridging the gap between these trough sections by an intermediate trough section is to split the I angle between said trough sections, and eliminate abrupt turns from one trough section to another,

to prevent the piling up of material at'the turn.

' The intermediate trough section 24 has a stub shaft 25 secured -to and depending from its bottom and journaled in an upper frame member 21; of the ball frame I6 (see Figure 2). The opposite end of said intermediate trough section underlaps the'forward connecting trough section 19 and has'a bearing member 29 secured thereto and depending therefrom, which is journaledin a control arm 30, on a bearing3l. Said control arm is in turn mounted on an upper frame 32 .the ball frame 20 (see Figures 2 and 3).

The-bearing member 29 is hollow andits inner periphery has a concave bearing surface which is adapted to be engaged by a convexly formed bearing member 34, mounted on a stub shaft 35, which 18 secured to and depends from the bottom of the or l rear end of the forward connecting trough section I 9. A retaining plate 38 is secured to the lower end of said shaft, to hold said bearing member on said shaft. Thus a ball and socket mounting is provided between the intermediate 5 trough section 24 and the forward connecting trough section I9, permitting said'trough section and the trough section H to pivot about a longitudinal axis and to follow a laterally pitching seam without causing twisting of said trough section or binding of the parts of the swivel.

The control arm extends from the stub shaft in a direction towards the center of the ba se I2 and has a rearward bifurcated guide portion 36, which slidably engages a guide roller-311:5 mounted on the upper end of'the stud t t-and; forms a rectilinear guide for said connecting and driven trough sections. The opposite end; Qf';'$i( 1' control arm extends in advance of the stub shaft 35 and has connection with the connecting trough section I9, adjacent its-folgward end, by mee of i a l l eeke eeeee ti-ea e iieeie generally by reference character 3 I It may be seen from the foregoing that when theforward driven trough section, I laterally with respect to thebase lg, pivotal move; m n thereof l be en re edveri lletentral arm 30, which will cause said ;trou g h sectionto pivot about the axis of, the roller .37. At the e time the ball frame 20 willhe swung bysaid on}. at

trolarm about said axis. 'Thus, upon-reciprocation of the conveyer, the guideportion 3 will reciprocably move along the roller 3] and willgbe guided by said roller for longitudinal slidable;

movement, with respect tether-base, It, any- 5 side thrusting motion transmitted ;to'thetrough section I l by the trough section I0, onvice versa, caused by the fact that the trough section; ll, isat an angle to the long itudinalicenter e of,- saidtrough section III- and is drivenrbysa mentioned trough section, will i be trans be altered i without, departing from thespirit and:

scope thereof. Furthermore, Ido-nQttWish-to' construed as limitingmy invention ,to he. spe fic; embodiment illustrated; excepting as, it, may be, limited in the appended claims.
